Product Introduction : Key Benefits.
Super Spe Speed ed The new Samsung washing machine’s Super Speed feature significantly reduces laundry times.* The big drum means clothes can be tumbled and agitated more effectively, effectively, while Speed Spray technology shoots cleansing jets of water at them, so they get clean faster faster.. Rinsing jets then shower them with clean water water.. Its VRT Plus system also ensures that the drum is balanced well, so spinning times are reduced.

ALW ALWAYS USE HE Detergents
When using the proper amount of detergent in soft water with “clean” clothes, it is possible to t o get over-sudsing.
Unless clothing is “dirty”, in soft water use ½ or less of the recommended detergent.

Individual valve operation may be tested in Quick Test mode (see Fast-Track) while in Test Test mode turn on the valves and measure 120VAC at each valve. Voltage comes from relays on Main PCB
Resistance should be approx. 1.20 kΩ – 1.25kΩ
Check for valves that are stuck ON (Quick (Quic k Test Test mode) mod e)

The water valves are a complete assembly. assembly. This means that if one valve goes bad, the entire valve cluster is replaced as one assembly. You can enter the Quick Test Mode and turn on the water valves, after doing so test each valve for 120V. If a valve measures 120V the valve is good. If no voltage is found replace the complete assembly.
Test in Quick TEST Mode. Refer to fast track for more details

Noise / Vibr ation
Check deformation of the leg frame bottom Check if the unit is level 36
Noise / Vibr ation
Check the assembly status of the bolt. If the bolt is loose, tighten it. When there is an abnormal noise, have the rotor disassembled and check for anything that may have been absorbed by the rotor magnet.
37
Noise / Vibr ation
If you get a Jet Engine noise during spinning mode, enter the test mode and put into a spin to confirm the noise during high speed. Replace the Tub back
38
Noise / Vibr ation
Check frictional noise between parts of the frame. Shake the tub back and forth to check where where the t he noise is coming from. Inspect the main parts from which noise is generated. Add sponge to frictional part of the frame-front or to the noise generating part.

Models with wrinkle prevent option may create some confusion for the customer. customer. After the unit stops drying drying it will continue to spin/stop this is normal to prevent clothing from wrinkling the unit will continue to spin and stop for a while. The customer may complain about the unit not stopping or spinning for no reason (Please explain to the customer and and check this option)
Things to know – Clo Cl o g g ed Vent
Clogged Vent – Clogged vents will will prevent the clothes from drying properly – Make sure the vent is clear of debris and lint build-up build-up – Put your hand on the vent and check if it gets warm – Disconnect & show the customer the unit working
